140 Journal of the Asiatic Sosiety of Bengal. [May, 1905. 
The synonomy of the Indian species of Tachydromus, like that 
of many other genera, has been rendered obscure by imperfect 
descriptions. At least three closely related forms must be recog- 
nized as occurring within or near the borders of British India. 
They are (1) T. sewxlineatus, Gray, recorded from Assam, Burma, 
Siam, the Western Himalayas, the Siamese Malay States, S. 
China, Sumatra, Java, Borneo, etc.; (2) UT. septentrionalis, Gthr., 
known from S.-W. China and here recorded from Assam, and (3) 
T. tachydromoides (Schleg.), formerly believed to occur in Assam 
but probably confined, so far as our knowledge goes, to China, 
Korea and Japan. A very distinct species, J’. smaragdinus, Bler., 
from the Loo Choo Islands is represented in the Museum by a 
specimen given by the late Dr. J. Anderson. 
T. tachydromoides was apparently included in the Indian 
fauna by Boulenger because he regarded it as synonymous with 
T. haughtonianus, which was described later. He also regarded 
T. septentrionalis, Gthr., at the time when he wrote his volume in 
the “ Fauna,” as identical with Schlegel’s species; but more 
recently he has pointed out that Giinther’s species is really distinct, 
though very closely allied to the other. An examination of Jer- 
don’s type in the Indian Museum shows that it is merely a speci- 
men of 1. septentrionalis, and, therefore, as Boulenger’s more 
recent views seem to be correct, the name 7’. tachydromoides must 
be crossed out from the list of the Indian Lizards and T. septen- 
trionalis inserted in its place. 
Apparently the only specimen of 7’. haughtonianus recorded 
was the type, which I have examined. It is distinguished from 
specimens of 1’. tachydromoides by the absence of granules. 
between the supraoculars and superciliaries and of a shield 
between the supraocular and the loreal. From 1. sealineatus 
it differs in having five rows of dorsal scales and a distinctly 
more elongated head. There is only one femoral pore on each 
side, but no small scales separate the outer rows of lateral plates. 
The specimen has four pairs of chin shields developed quite 
symmetrically—-a condition I find also in two young specimens of 
1’. sealineatus, out of twenty-seven, young and adults, of this 
species examined. The coloration and proportions (except as. 
regards the head) are practically identical with those of 
T. sexlinestus. 
LaAceRTA viripis (Laur.) 
L. viridis var. major, Blgr., Cat. Liz., iii, p. 17. 
The Museum possesses three specimens from Mount Hermon 
(J. Anderson) of Boulenger’s variety major. As there is in the 
British Museum a specimen of the variety (Gray’s species) 
stiigata from the same locality and collection, the two varieties. 
must occur together. The only specimens of strigata in the 
Indian Museum come from Persia (W. TY. Blanford) and are: 
immature.
